Because the sodium lamp is delayed during switching, it is not suitable for frequent action switching. Therefore, if the lamp is installed in the same light box as the PL lamp, the detection time of the base board will be delayed. Referring to the sixth figure, China's Announcement No. 525781 "Light Box for LCD Device Testing Device", shown by symbol 80 in the figure, mainly includes: a cover 81 having an opening 811; two cover plates 82, which can be opened and closed It is pivoted on the edge of the opening 811 of the cover 81. When the two cover plates 82 are closed, the opening 811 15 is closed. A drive component 83 is connected to the two cover plates 82 to drive the two cover plates. 82 generates opening and closing actions; a plurality of sodium lamps (not shown) are arranged in the cover 81; a plurality of PL lamps 84 are respectively arranged on the outer end faces of the two cover plates 82; thereby, the driving assembly 83 is operated to By driving the two cover plates 82 to open and close, the effect of switching light sources can be achieved in the same light box 80. 20 Of course, when the light box 80 is opened, the weight of the PL lamp 84 is too heavy, which may cause the cover plate 82 to shake when it is pivoted and become loose. This also makes the PL lamp 84 prone to failure. .

In order to achieve the purpose of the previous disclosure, this creative light box with switchable light sources mainly includes: a housing with an opening at one end; a plurality of first light sources, and the first 5 light sources are arranged in the housing, and the first light sources A light source is projected outward through the opening; a plurality of second light sources are arranged in the housing at equal intervals, and the second light sources project the light source outward through the opening; a plurality of shading groups are provided in the housing and located in the first Between the two light sources and the opening, each of the shading groups has two shields, the two shields are respectively pivoted on two sides of a second light source, and the two shields 10 boards can be between a shield position and an open position Pivot, when the two shielding plates are in the shielding position, the light source of the second light source will be blocked from seeping through the opening; and when the two shielding plates are in the open position, the light source of the second light source will pass through the opening The opening projects outward; a plurality of driving devices are provided in the housing and are respectively pivotally connected to two shutters of the shading group, and the driving devices are used to drive the two 15 shutters; The shell and the two diffuser plates are parallel and spaced apart to enclose The opening surface. As a result, the light box has fewer components and is less likely to be damaged during use, which can extend the life of the light box. 20 [Embodiment] A preferred embodiment is described below with illustrations: The first figure is a front view of a preferred embodiment of the present invention; the second figure is a top view of a preferred embodiment of the present invention; The third figure is a side view of a preferred embodiment of this creation; -6- M265606 _ New Manual A Continuation Page The fourth figure is a schematic diagram of a preferred embodiment of this creation; and the fifth figure is similar to the fourth figure Action diagram. Please refer to the first to third pictures. The light box 5 10 with switchable light source in this creation, as shown in the figure, the light box 10 mainly includes a housing 20, a plurality of first light sources 30, four second light sources 40, and four shading groups. 50. A four-drive device 60 and a two-diffusion plate 70. The relative relationship between these components and the structure thereof are detailed as follows: The casing 20 has an opening 21 at one end. 10 The first light sources 30 are arranged in the housing 20 at equal intervals, and the first light sources 30 are PL lamps in this embodiment. The light source projected by them can pass through the opening 21 of the housing 20 Reveal. The four second light sources 40 are arranged in the housing 20 at equal intervals, and the second light sources 40 are sodium lamps in this embodiment, and the light source of the projection can be transmitted through 15 the opening 21 of the housing 20 . In accordance with the fourth and fifth figures, the four light-shielding groups 50 are disposed in the housing 20 and located between the opening 21 of the housing 20 and the second light source 40. The light-shielding groups 50 are respectively connected with one The second light source 40 corresponds. Each of the light shielding groups 50 has two shielding plates 51 located on two sides of the corresponding second light source 40, and each of the 20 shielding plates 51 is composed of a cover sheet 511 and a guide sheet 512, and the cover sheet 511 and the guide sheet The sheets 512 are each perpendicularly connected to each other at one end, thereby making the shutter 51 substantially L-shaped. In addition, each of the shielding plates 51 is pivotally mounted on a fixing plate 22 in the housing 20 with a connection point of the cover piece 511 and the guide piece 512 thereof, so that each of the shielding plates 51 can be installed in one of the housing 20. The shielding position and a new M265606 manual, pivoting between the open positions of the continuation pages; when the two shielding plates 51 are in the shielding position, the two covers 51, 1 will be blocked between the second light source 40 and the opening 21. When the two shielding plates 51 are in the open position, the two cover pieces 511 are pivoted away from the second light source 40 and are in an open state. 5 The four driving devices 60 are disposed in the casing 20 and respectively correspond to a shading group 50. Each of the driving devices 60 has an air cylinder 61 and a flat plate 62. The air cylinder 61 is provided at the corresponding end of the light-shielding group 50, and has a piston rod 611 that can be linearly reciprocated, and the flat plate 62 is connected to the piston rod 611 with a middle section of the plate body. In addition, the The two shielding plates 51 of the light-shielding group 50 are respectively pivoted on the flat plate 62 through one end of the guide piece 512, and the two guide pieces 512 are located on the two sides of the piston rod 611; thereby, when the air cylinder When 61 is actuated, the piston rod 611 will drive the two shutter plates 51 through the flat plate 62. The two diffusion plates 70 are spaced in parallel to cover the openings 15 21 of the casing 20. When the first 30 or the second light source 40 projects light outward through the opening 21, the two diffuser plates 70 can be used to refract a point light source into a surface light source, so that the first light source and the second light source project outward. The light is more even. Since the application principle of the diffuser plate is a known technique, it will not be described in detail here. 20 As shown in the fourth figure, when the operator wants to detect the liquid crystal substrate with the PL lamp, he drives the driving devices 60 so that the piston rod 611 of each of the air cylinders 61 protrudes outward. At this time, the flat plate 62 It will drive the two shutters 51 to pivot, so that the two shutters 51 are in the shielding position and are in a closed state. The light of the second light source 40 is blocked by the two cover plates 511 and cannot be transmitted through the opening 21. -8- M265606!-New manuals are continued. Conversely, as shown in the fifth figure, when the operator wants to detect the liquid crystal substrate with a sodium lamp, the first light source 30 is first turned off, and the driving devices 60 are activated at the same time, so that the piston rods 611 of the air cylinders 61 are directed toward Retracted inside, at this time, the flat plate 62 will drive the two shutters 51 to pivot to the open position, and it is in an opened state of 5, so that the light of the second light source 40 can be directed through the opening 21 to Out. From the above structure and description, we can see that this creation has the following advantages: First, the detection of sodium and PL lamps can be done in the same light box, and there is no need to switch sodium lamps continuously. Therefore, there is no problem with sodium lamp turn-on delay. Can save operation time. 2. Compared with the conventional light box, the light box with switchable light source in this creation has a simple structure and is less likely to be damaged in use, so it has a longer service life. -9- M265606-New instruction manual / continued page [Simplified description of the drawing] The first drawing is a front view of a preferred embodiment of this creation.
